WIRE-CLAMP-FASTENING MEANS.

Specification of Letters Iatent.

Patented July 20, 1920.

Application filed May 22, 1919. Serial No. 299,066.

To all whom it may concern:

Be it known that I, CARL H. VERNER, a citizen of the United States of America, and a resident of IVaterloo, Blackhawk county, Iowa, have invented certain new and useful Improvements in ire-Clamp- Fastening Means, of which the following is a specification.

My invention relates to improvements in wire-clamp fastening-means, and the object of my improvement is to supply means for adjustably and releasably fastening wireclamps about the form-boards and support ing timbers therefor used to receive and mold concrete for walls or the like constructions.

This object I have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which Figure 1 is an illustration partly in plan and partly in horizontal section of the form-boarding and supports of a mold for a concrete wall, showing the parts thereof clamped together by my improved fastening-means; Fig. 2 is an enlarged perspective view of one of my said wire fastening-devices, and Fig. 3 is a plan View of the bottom of the base-plate of one of said devices.

Similar numerals of reference denote corresponding parts throughout the several views.

Referring first to said Fig. 1, the numera 12 denotes parallel form-boards, spaced by separator boards 13, and between which concrete 14 is deposited to form a wall.

The numeral 15 denotes vertical timbers set at intervals along and in contact with the outer faces of the boards 12 to support same.

Before deposition of the concrete 1 1 between the form-boards 12, wires 16 are used to clamp the timbers 15 and boards 12 against the separator boards 13. The boards 12 are orificed on both sides of each timber 15. A piece of wire 16 is bent medially around each timber 15, its members then passed through the orifices in the 0pposite boards 12 to project a distance beyond the mold.

The projecting ends of the wire 16 are then fastened to the abutting timber 15 by my improved fastening-device.

This device comprises a base-plate 1 having parallel longitudinal ribs 2 which supply a troughed seat so that the base-plate may be mounted upon the outer part of the timber 15. Upon the base-plate 1 are spaced integral lugs 3, orificed in line to receive a rotatable shaft 1 provided in each end without the lugs with small transverse orifices 5.

One end 8 of said shaft is squared to fit a socket-wrench. A hub-sleeve 6 is fixed upon said shaft between the lugs 3 by a traversing pin 11 and has thereon a ratchetwheel 7 whose teeth are engaged movably by a pawl 10 pivoted in lugs 9 on the baseplate. As the pawl 10, when the device is in use, is above the ratchet-wheel, it is retained in engagement therewith by gravity, but a spring may be applied thereto to keep it in engagement, in a well known manner.

In practice, the extremities of the wire 16 are passed through the orifices 5 in said shaft 4, and the shaft rotated by means of I a wrench to wind the wire about it until the timbers 15 are tightly compressed and held against the form boards 12, and the pawl 10 holds the ratchet-wheel 7 and said shaft securely.

When the wall 14: has been completed, the device may be easily removed and the wire ends released, the timbers 15 and formboards 12 displaced, and the wire 16 cut off close to opposite sides of the wall.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is:

In a device of the character described, a flexible element formed into a U-shaped loop, whose members traverse alined orifices in spaced inter-stayed mold-boards, and a strain-device positioned along one of the mold-boards having a longitudinally-channeled base-plate to fit a vertical cleat on one of said mold-boards and having spaced bearings, a rotatable shaft in said bearings, the shaft having engaging-means to receive and hold the extremities of said members when the latter are wound about the shaft, placing the members simultaneously under equal longitudinal strain, and means for releasably holding the shaft in an adjusted position.

Signed at Waterloo, Iowa, this 6th day of May, 1919.

CARL H. WERNER.
